Robertshaw White Universal Gas Range Knob - 4590-503

Robertshaw White Universal Gas Range Knob - 4590-503

Replace a worn gas range knob only after matching shaft and pointer indexing with this Robertshaw White Universal Gas Range Knob - 4590-503. Robertshaw Slip-Fit knobs are designed to be used with dial overlays and 4-way insert adaptors so a technician can match many common OEM knob applications.

Compatibility: Universal/spec-match replacement for gas ranges where the Robertshaw Slip-Fit knob, selected insert, shaft style, dial overlay, color, and pointer alignment match the original control.

Fitment Families: Knob fit is controlled by shaft diameter, D-flat or stem shape, insert selection, stem depth, pointer direction, OFF position, and overlay markings. It is not model-specific OEM fitment unless the appliance lookup confirms it.

Fitment / What To Verify: Verify shaft style, insert selection, overlay markings, knob color, diameter, stem depth, and OFF/pointer alignment before ordering. Control knobs are high-return parts when ordered by appearance alone.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Knob is cracked, missing, melted, stripped, loose on the shaft, or no longer turns the gas valve reliably.
• Visible/Sensory Cues: Damaged internal socket, loose fit, unreadable markings, heat discoloration, cracked skirt, or pointer alignment that does not match OFF and burner settings.

Pro Tip: Set the valve to OFF before installing and verify pointer/overlay alignment through all settings. Incorrect indexing can create a safety issue on gas controls.
